SOURCE: Sears 19 hp twin 42 inch tractor, won't start if hot
Hi
Two things come to mind. First it could be not getting enough fuel when hot due to carb adjustment being too lean. That could be that the float level in the carb is set too low or the low speed jet is set too lean. When cold the choke circuit in the carb supplies the extra fuel required.
Second in some enjines that have low compression they start cold but when hot the compression drops below 60 psi and makes starting very difficult until engine cools down.
I suspect a fuel problem.

It sounds to me that you need a new mower deck drive belt, or your blades need sharpening. If the blade edges are rounded, they won't cut butter... Also, when mower is off, check mower deck drive pulleys to make sure you don't have any that are locked up or are dragging. You can check this by pulling the belt away from pulley and spinning the pulley by hand. MOWER MUST BE OFF before attempting any of these checks. You would be surprised how many people would try this with the mower running.
Hope this helps

Is the belt on the pulleys ? If so your cable is broke its what engages deck belt

Hello jon3208:
>>The Following is a Basic Instruction File I made for this. Any Input is Appreciated. I Usually Suggest you Check the Following in this Order for a Problem like yours. **CHANGE ANY SPRING STYLE HOSE CLAMPS TO THE SCREW STYLE HOSE CLAMPS*** 1- Check the Gas Tank Cap and Ensure it is Venting the Tank. A Vacuum Builds in the Tank and the Gas Flow Stops or Slows (15 to 45 Minutes and if the Small Grainular Sand is in the Tank it can Take Several Days of Constant Running to Bring All the Sand Particales to the Tank Outlet Port) to a Point it Shuts Off the Engine. 2- Operate the Equipment Until it Quits (15min to 1hr). Then Immediately Check for Fire from the Plug. If the Plug is Firing, then 3- Check the Carburetor Solenoid. If the Carburetor Shut Off Solenoid has Current, then Remove the Carburetor Solenoid and Go to the Hardware Store. Purchase a Bolt of the Same Diameter and Threads. It Needs to be 3/4" Long. Put this Bolt in Place of the Solenoid. If this Corrects the Engine Problem, then Replace the Solenoid. ***NOTE: THIS IS FOR CHECKING THE SOLENOID ONLY I NEVER SUGGEST YOU OPERATE THE ENGINE WITH THE SOLENOID OUT OF THE CARBURETOR EXCEPT FOR TESTING PURPOSES*** Sometimes the Plunger is Moving, Just Not Far Enough to Allow the Gas to Enter the Jets. 4- Depending on the Model Mower, it can Also be the Pickup Tube in the Gas Tank. If No Fire, then Remove the Shut Off Wire from the Coil and Check for Fire. If Still No Fire, then the Ign Module or Coil is Bad. **Even if the Coil is New of Fairly New, it can Still be Bad.** On JD Mowers; Remove the Igniter/Module and the Coil and have the Local JD Dealer Test them.
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.
Good Luck
Respectfully
